Under the initiative, either Singapore Changi Airport (SIN) or Seletar Airport (XSP) will be used as a testbed to co-develop what CAAS describes as a “comprehensive readiness framework” for integrating open-fan engines and next-generation aircraft into existing airport operations. The work will cover aircraft and engine design considerations, airport infrastructure modifications, changes to operational procedures, safety standards and regulatory processes.

Hehe, I expect they’re thawed before the test, but who knows!
The GE9x is shown being tested by launching a block of solid ice at the fan, and it shreds the ice!
